Description

[Detailed description of the invention] This invention relates to a deck plate support structure.

In conventional steel frame structures, upper and lower connecting fittings are protruded on the vertical line of the column side at a predetermined interval, and one end of the beam is held by these connecting fittings, and a pair of decks are connected to each other. With the plates abutted against each other, their abutting ends are placed on the beam, and concrete is poured onto the deck plates to form a subfloor. However, since the upper connecting fitting is located at the upper end of the beam, the corner of the deck plate is cut out to prevent the deck plate and the connecting fitting from overlapping, and as a result, the corner of the deck plate is not supported by the beam. This has caused a problem in that the supporting strength of the corner portion of the deck plate decreases.

Therefore, the object of this invention is to provide a deck plate support structure that can support the deck plate with sufficient strength even at its corner portions.

An embodiment of this invention will be described with reference to FIGS. 1 to 4. Figure 1 shows the frame structure of the girder side of a steel frame building.Columns 2, 2 are erected on an underground beam (foundation) 1, and between these columns 2, 2 the upper
A second floor beam 4 is bridged via lower connecting fittings 3 and 3', and the inner corner of the column 2 and underground beam 1 is reinforced with a brace 5'.

To explain in detail the connection structure of the second floor beam 4 to the pillar 2, as shown in Figures 2 to 4, Hi-Split (product name) manufactured by Hitachi Co., Ltd. is used as the upper and lower connecting fittings 3 and 3'. . These upper and lower connecting fittings 3, 3' have horizontal pieces 3b, 3b' connected to the center of each vertical piece 3a, 3a' in a T-shape, and these vertical pieces 3a, 3a' and horizontal pieces 3b, 3b. ' bolt insertion holes are provided at the top and bottom of the column 2 at a predetermined interval, and each vertical piece 3a, 3a'
along the flange 2a of the bolt 5 and nut 6.
Connect to pillar 2 by.

The second floor beam 4 is made of I-shaped steel, and its one end is inserted between the horizontal pieces 3b and 3b' of both connecting fittings 3 and 3'.
Fix with bolts 7 and nuts 8. in this case,
A hat-shaped plate holder 9 is interposed between the second floor beam 4 and the upper connecting fitting 3. That is, this plate holder 9 has the upper flange 4 of the second floor beam 4 in its groove.
a are fitted and welded, and both outer flange pieces 9a are provided protruding from both outer sides of the second floor beam 4. Then, the upper surfaces of both outer flange pieces 9a are aligned at the same height as the upper surface of the second floor beam 4.

The pair of deck plates 10, 10' have notches 10a, 1 at the corner portions corresponding to the upper connecting fittings 3.
0a' is formed. These deck plates 10,1
0' is a state in which the respective opposing end surfaces are abutted against each other, and the respective abutting ends 10b, 10b' are 2
While being mounted on the floor beam 4, the above-mentioned notch 10
The upper connecting fitting 3 is inserted into the openings 10a and 10a', and its cutout edges 10c and 10c' are placed on both outer flange pieces 9a of the plate holder 9. Then, concrete is poured onto these deck plates 10, 10' to form a subfloor. In addition, in FIG. 3, 11 is a spacer, and 12 is a plate for fixing concrete.

As a result of this configuration, deck plate 1
0, 10' center abutting ends 10b, 10b'
Not only can it be supported by the floor beam 4, but also the cutout edges 10c, 10 of the deck plates 10, 10'
Since c' can also be supported by both outer flange pieces 9a of the plate holder 9, the deck plates 10, 10' can be supported with sufficient strength not only at the center but also at the corners.

As described above, the deck plate support structure of this invention consists of a column, upper and lower connecting fittings protruding at a predetermined interval on a vertical line on the side of the column, and one end of which is held by the connecting fitting. a beam, a plate holder interposed between the beam and the upper connecting metal fitting and having both sides projecting outwardly from the beam; A pair of parts are placed on the upper surface of the beam, and the upper connecting fitting is inserted into a notch formed on one side of the butting ends, and the edges of the notch are placed on both sides of the plate holder. Since the deck plate is equipped with a deck plate, the deck plate can be supported with sufficient strength even at its corner portions.
